It’s right at the very beginning. You can hear the F-16s coming back one after another right behind Amir as he stands on the Golan Heights. He’s not authorized to tell exactly what they hit but he gives a clue. They may have come from 2 directions, I’m not clear on that. Some from Israel itself and some from Lebanon.
How do you know they planes are F-16s? The IAF operates other planes like the F-35 and so on. How do you know what you are hearing/seeing is actually a current operation?
If a strike can be seen it must have been daylight so the targets were lightly defended - if at all. You do realize that the IAF has a habit of striking abandoned fortifications?
If a strike can be seen, then it is not an attack anyone is trying to be secretive about - most IAF northern strikes that matter (like on Iranian missile dumps) are secretive and cannot be seen from the Golan.
Believing anything - news, rumors etc - from the ME is a fools errand unless you have actual evidence - bodies, photos and the like.
